Hauv kev miniaturization thiab txheej txheem txheej txheem txheej txheem ntawm cov khoom siv hluav taws xob niaj hnub, PCB (luam tawm cov boardrcuit Court lub luag haujlwm) ua lub luag haujlwm tseem ceeb. Raws li tus choj ntawm Cheebtsam hluav taws xob, PCB ua kom muaj kev sib kis ntawm cov cim thiab cov khoom siv tau ruaj khov. Txawm li cas los xij, thaum lub sijhawm nws cov txheej txheem tseeb thiab ua haujlwm nyuaj, ntau yam tsis xws tshwm sim los ntawm lub sijhawm, cuam tshuam rau kev ua tau zoo thiab kev ntseeg tau ntawm cov khoom. Kab lus no yuav tham nrog koj qhov tshwm sim ntawm PCB Circuit Coffs thiab cov laj thawj tom qab lawv, muab cov lus qhia ntxiv "Kev tsim kho cov qauv thiab khoom siv hluav taws xob.
1. Luv Circuit Court thiab Qhib Circuit Court
Kev Ntsuam Xyuas:
Cov qauv tsim qauv: Kev tsis saib xyuas lub sijhawm tsim cov theem tsim, xws li cov teeb meem nruj me ntsis ntawm cov khaubncaws sab nraud povtseg, tuaj yeem ua rau luv lossis qhib.
Cov txheej txheem tsim khoom: Ua tsis tiav Etriing, drilling disterniation lossis solder cuam tshuam los tiv thaiv cov seem ntawm lub ncoo yuav ua rau Circuit Court lossis qhib Circuit Court.
2. Sonder daim npog tsis meej
Kev Ntsuam Xyuas:
Uneven txheej: Yog tias cov quav tiv thaiv tsis tshua muaj kev faib tawm thaum lub sijhawm txheej txheej, lub tooj liab cov kev pheej hmoo ntawm cov voj voog luv luv.
Kev Kho Mob Tsis Txaus Siab: Kev tswj tsis raug ntawm ci lossis lub sijhawm ua rau cov joffer tiv thaiv kom tsis muaj kev tiv thaiv, cuam tshuam rau nws txoj kev tiv thaiv thiab kav ntev.
3. Puas muaj qhov muag tsis zoo npo luam ntawv
Kev Ntsuam Xyuas:
Luam Ntawv Raug Tsim: Lub vijtsam luam tawm cov khoom siv tau tsis muaj teeb meem lossis kev ua haujlwm tsis raug cai, ua rau muaj qhov muag plooj, ploj lossis offset cov cim.
Ink Cov Teeb Meem Zoo: Kev siv cov mem kua qis lossis tsis muaj txiaj ntsig ntawm tus cwj mem thiab cov phaj tsis zoo ntawm lub number case thiab cov phaj cuam tshuam rau kev pom meej thiab cov nplaum ntawm lub logo.
4. Lub qhov tsis xws luag
Kev Ntsuam Xyuas:
Drilling kev sib txawv: tho kev hnav lossis qhov chaw tsis muaj tseeb ua rau lub qhov taub uas loj dua los yog hloov chaw.
Cov kua nplaum tsis tiav: Cov khoom lag luam uas muaj dua tam sim no tsis muaj kev txav tawm, uas yuav cuam tshuam rau tom qab vuam zoo thiab ua haujlwm hluav taws xob.
5. Interlayer sib cais thiab ua npuas ncauj
Kev Ntsuam Xyuas:
Thermal Kev ntxhov siab: qhov siab kub thaum lub sij hawm tiv thaiv shodering soldering yuav ua rau muaj kev tsis sib xws ntawm cov khoom sib txawv ntawm cov khoom sib txawv, ua rau sib cais ntawm cov khaubncaws sab nraud povtseg.
Nws noo penetration: underbaked PCbs nqus noo noo ua ntej sib dhos, sib sau ua npuas thaum solding, ua rau sab hauv kev npau taws.
6. Neeg tsis zoo plating
Kev Ntsuam Xyuas:
Uneven plating: tsis sib luag ntawm qhov ceev tam sim no los yog tsis muaj kev sib xyaw ntawm cov plating cov txheej txheem ntawm cov tawv me me ntawm cov txheej txheem tooj liab, cuam tshuam nrog kev ua haujlwm zoo thiab solderability.
Cov pa phem: ntau cov impurities nyob rau hauv cov plating daws cuam tshuam qhov zoo ntawm cov txheej thiab txawm tias cov pannes lossis cov chaw tawv.
Kua daws lub tswv yim:
Nyob rau hauv teb rau cov kev tsis txaus siab saum toj no, kev ntsuas coj tau suav nrog tab sis tsis txwv rau:
Optimized Tsim: Siv cov CAD siab dua software rau kev tsim qauv ncaj ncees thiab raug tsim qauv rau kev ua lag luam (tsim qauv rau kev ua neeg tsim khoom) tshuaj xyuas.
Txhim kho cov txheej txheem tswj: ntxiv dag zog saib xyuas thaum lub txheej txheem tsim khoom, xws li siv cov khoom siv siab thiab nruj me ntsis kev tswj hwm cov txheej txheem tsis sib xws.
Xaiv cov khoom xaiv thiab kev tswj hwm: Xaiv cov ntaub ntawv raw zoo thiab ua kom muaj cov khoom khaws cia kom tiv thaiv kom tsis txhob muaj cov khoom ntub lossis tsis zoo.
Kev Soj Ntsuam Zoo: Siv ib qho kev tswj hwm zoo, suav nrog Aoi (tsis siv neeg soj ntsuam), x-ray kuaj, thiab lwm yam, los xyuas thiab kho kom raug raws sijhawm.
Los ntawm kev nkag siab tob ntawm cov pcb Circuit Coffic boards thiab lawv cov chaw tsim khoom siv tau cov teeb meem zoo thiab muaj kev ntseeg tau ntawm cov khoom siv hluav taws xob. Nrog kev nce qib nruam ntawm kev sib tw thev naus laus zis, muaj ntau txoj kev sib tw hauv thaj chaw, tab sis los ntawm kev tswj hwm kev tshawb fawb thiab thev naus laus zis tau kov yeej ib qho los ntawm ib qho.
